As a controversial technology, nuclear power is both beneficial and risky. Therefore, its smooth development should be based on public acceptance. So it's meaningful to modify the Theory of Planned Behavior (TPB) and apply it to the construction of the nuclear power acceptance model. This research shows that trust, subjective norm and perceived behavior control can significantly influence behavioral intentions, with the effect of trust being the strongest. Publi?s "perceived benefits" and "perceived risks" of nuclear power can both significantly influence their trust and behavioral intentions. But they are far more cautious with the risks than excited about the benefits.
